Bond and Behavior of Composite Reinforcing Bars in Concrete

Abstract

Abstract Wood, concrete, steel, and combinations thereof have traditionally been used in civil infrastructure. However, each of these materials has its own drawbacks that range from susceptibility to environmental attack to the large deadweight of the material itself. Steel reinforcing bars, commonly known as rebar, although extensively used for reinforcement of concrete, are susceptible to corrosion and the rapid deterioration of the structure. A number of other factors including chemical and corrosion resistance, better fatigue performance and increased durability in adverse environments, lower overall life-cycle costs, lighter construction material, potential ease of assembly and installation, reduced costs of transporting modules to site, use of modular construction, design flexibility, and overall lower energy consumption have motivated the investigation of the use of composites in civil infrastructure. The present paper focuses on the results of the use of composites as reinforcements in concrete be...
